The Completions & Production Study Group's goal is bring together a technical and operations community to discuss the technology of today and how to to continue to develop this into the future.


Our group meets monthly during "lunch-and-learn" presentation events led by operators, service companies, and university speakers. We also have a yearly "symposium" all-day event  where multiple speakers discuss all things completions and production. We are grateful to have NexTier sponsor all of our monthly events at their headquarters on the west-side of Houston, as well as our yearly symposium event. 




Thank you to our group sponsor:
